"Momo" by Michael Ende
By Michael EndeThe main character of Michael Ende’s Momo is a nine year old girl who, after noticing subtle changes in her friends and neighbors, quickly finds herself battling the mysterious and evil Men in Grey. Who are these ominous, bald “salesmen” who go around convincing just about everyone that by saving as much time as possible and depositing that time in the Men in Grey’s bank, they will get it back with interest at some later point? No one really knows.
